The opening and open in dot and dash lines, and parts 12 of the shell 10 is cont-rolled by a door 16 said door is somewhat larger than the open ing 12 to present marginal portions 17 and 18 which overlap portions 19 and 20 respectively of the wall 11. Tongues 21 are secured to the edge portion 17 of the door 16 in spaced relationship, and each extend downwardly through an opening 22 in the portion 17, and through an opening 23 in the edge portion 19 of the wall 11, said tongue engaging the under side of the portion 19 when the door is in the closed position, as shown most clearly in Fig. 8. Hubs or sockets 24 are secured to the edge portion 17 of the door, and are disposed respectively at oposite sides of the door in axial alignment or a purpose to appear.

In order to latch the door 16 in a closed position and also to release the door so that it may be swung to an opened position there is provided means presently to'be described.

7 A bar 25 is arranged on the edge portion 18 of the door and is guided for sliding movement by guides 26 secured to said portion 18. The bar 25 has limited movement by virtue of shoulders 27 and 28 formed on the bar 25, the shoulders being engageable with the guides 26 in the movement thereof, the shoulders 27 limiting the movement of the bar 25 in one direction and the shoulders 28 limiting the movement of the bar in an opposite direction. Thebar 25 has a plurality of equally spaced slots 29. Latch elements 30 are arranged on the portion 18 of the door 16 for turning movement, and are adapted to cooperate with the bar 25. Each element 30 includes a laterally projecting pin 31, and a laterally projecting lug 32. Each element 30 is disposed so that the pin 31 thereof will enter one of the slots 29. The portion 20 of the wall 11 has a slot 33 through which the lug 32 of the related element 30 pass.

Use is made of a peavey consisting of a bar 34 the lower end of which is tapered and a hook 35 pivotally connected with the bar 34 near the lower end thereof. The bar 25 has a notch 36, and the adjacent end of the shell 10 has an opening to present a socket 37. The

- wave 1 serves for movin the bar 25 in o osite directions for the purpose of latching and releasing the door 16. This is accomplished by entering the lower end of the bar 34 in the socket 37, and entering the hook 35 in the notch 36, whereupon the bar 34 may be manipulated to impart sliding movement to the bar 25. In one position of the bar 25, the lugs 32 of the elements 30 will be in engagement with the portion 20 of the wall 11 and therefore hold the door 16 closed, as shown most clearly in Figs. 6 and 7. When the bar 25 is moved in the direction indicated by the arrow in Fig. 7 ,the elements 30 will be turned one-quarter of a revolution allowing the lugs 32 to pass through the slots 33.

l equently the door 16 maybe swung to [the open position.

The conveyor includes a main frame 40 built up of suitable structural elements such as angle or channel irons or tubular members riveted or welded together. The frame has secured thereto bearings 41 respectively at opposite sides in which the opposite ends of the shaft 13 are journaled respectively in or der to allow the shell 10 to rotate relatively to the frame. Each end of the frame 10 is provided with suitable means such as a coupler 42 whereby the conveyer may be coupled or hitched to a tractor or other power driven Vehicle. Each end of the frame 40 has a prop 43 pivotally connected as at 44 with the frame, there also being provided a jointed brace 45 having one end pivotally connected as at 46 with the prop and the opposite end being pivotally connected as at 47 with the frame. Each prop 43 serves when lowered to hold the related end of the frame 40 elevated, as shown most clearly in Fig. 1. Each rop 43 may be held in the raised position y any suitable means indicated at 48 on the frame.

In order to cooperate with the hubs or sockets 24 on the door 16 to enable it to be swung to the opened and closed positions there are provided thread-ed elements 49. Each element 49 threads in a hub 50 on a bracket 51 secured to the frame 40. Each element 49 has a trunnion 52 at one end, and the opposite end 53 being square to accommodate a crank for the purpose of turning the element 49. The trunnions 52 of the elements 49 are in axial alignment, and may be entered into the sockets 24 when brought into registry therewith. A latch device comprising a toothed rack 54 on one end of the shell 10 and a pivoted dog 55 on the frame 40 serve to prevent rotation of the shell in each direction, and in fact limit its movement in each direction to a point in which the sockets 24 will be in registry with the trunnions 52, when the dog 55 is in engagement with one of the teeth of the rack 54. It will now be understood that when the trunnions 52 are entered into the socket 24 the door 16 may be swung to the opened and closed positions.

In order to swing the door 16 to the opened and closed positions there is provided means presently to be described, or any equivalent means. In the present instance said means includes a hoisting rig including a frame 60 pivotally mounted as at 61 on the frame 40. The frame 60 has arranged thereon suitable pulleys 62. A suitably braced support 63 is arranged on the frame 40 and carries near the upper end thereof a bracket 64 on which is mounted a motor 65. The shaft of the motor 65 has secured thereto a drum 66. A cable 67 has one end thereof connected with the drum 66 and is wound on said drum, and also is passed around the pulleys 62, the free end of the cable being provided with a hook 68 for engagement with an eye or ring 69 on vent'it from swinging beyond certain limits.

The latch members 70 when engaged respectively with the pins 73 serve to hold the frame 60in the raised position for hoisting. The motor may be driven by current derived from storage batteries (not shown). It is also to beunderstood that any other means may be provided for operating the drum 66. A cradle 75 is arranged onthemain frame 40 at one end thereof, and is adapted to support the door 16 when it is detached from the shell It is to be understood that the door 16 will be held bythe cradle 7 detached from the shell while the shell is being loaded with material. After the shell 10 has been loaded the elements 49 are manipulated to enter the trunnions-52 into the sockets 24. The frame 60 is then raised and is held in the raised position by the latch members 70 which are engaged with the pins 73. The hook 68 on the cable is then engaged with the ring 69 on the door 16. The motor 69 is then started which will cause the door 16 to be swung to the closed position. The door 16 may then be latched in the manner explained hereinbefore. By unlatching the door 16 it may be swung to the open position in a similar manner, it being understood that the door swings under its own weight for a part of its travel. It is also to be understood that one or both of the props 43 may be brought into its or their propping position or positions to prevent movement of the main frame 40, it also being understood that the frame in being coupled to a tractor will also contribute to hold the frame 40 against movement.

In order that the shell 10 minus the door 16 may serve as a spreader and leveler of the material leaving the shell, as the conveyer is traveling along the ground there is provided a toothed rack 76 Which is secured to one of the end walls of the shell 10. The rack 7 6 is arcuate and concentric to the axis of rotation of the shell. The teeth of the rack 76 coact with the dog hereinbefore referred to to hold the shell in different positions relatively to the frame, and also prevent the shell from rotating when the conveyer is being moved along the ground. From Fig. 4 it will be apparent that the edge portion 19 of the cylindrical wall 11 serves as a leveling or scraping means, and that the same may be disposed relatively to the surface on which the shell travels, at different elevations. It follows therefore that fills or layers of various thicknesses may be laid by merely adjusting-the position of the shell 10. In Fig. 4 the dotted line 77 indicates the thickness of thelayer of material being laid with the parts in the relationship shown, and the dotted line 7 8 indicates the maximum thickness or depth of layer which may be spread or laid. lVhile using the conveyer for spreading and leveling the material, the door will be held by the cradle 7 5, and the door may remain in the cradle when the conveyer is traveling over the ground with the shell empty.

It is to be understood that the features of the invention are not restricted to the precise arrangement of parts shown and described, as details ofconstruction may be modified and rearranged without departing from the spirit of the invention, the scopeof which is limited only by the terms of the appended claims.
